Abstract
Official abstract text for this publication.
Control circuits and related methods are provided. One exemplary control circuit includes a solid state switching device for coupling to a first tap of a motor and a control device coupled to the solid state switching device. The control device is configured to switch the solid state switching device to apply a signal to the first tap in response to a demand for operation of the motor at a second parameter to operate the motor at the second parameter. The control device is also configured to switch the solid state switching device to apply a signal to the first tap in response to a demand for operation of the motor at a first parameter to operate the motor at the first parameter.
First claim
Opening claim text (preview).
What is claimed is: 1. A control circuit for a motor of a HVAC system, the motor including at least a first tap and a second tap, the motor configured to operate at a first parameter when the first tap is energized and at a second different parameter when the second tap is energized, the control circuit comprising: a solid state switching device for coupling to the first tap of the motor; and a control device coupled to the solid state switching device, the control device config…
